But it is not just Democrats who are opposed to the collection of such data by the federal government.

Mississippi’s Secretary of State, Delbert Hosemann, a Republican, said in an official statement that his reply to the commission would be “they can go jump in the Gulf of Mexico and Mississippi is a great state to launch from”.

Mr Trump set up the commission to investigate claims – unsubstantiated, but which he repeats – that millions of fraudulent votes cost him the popular vote in the 2016 presidential election.

He secured more votes in the all-important electoral college than his Democratic rival, Hillary Clinton, thus winning the presidency.

The aim is to “increase the American people’s confidence in the integrity of our election systems”.

Kentucky’s Secretary of State, Alison Lundergan Grimes, said she would not be releasing “sensitive personal data to the federal government”.

“Kentucky will not aid a commission that is at best a waste of taxpayer money and at worst an attempt to legitimise voter suppression efforts across the country,” she said in a statement.

The panel, described by Mr Trump as “very distinguished,” is chaired by Vice-President Mike Pence.

On Wednesday its vice-chair, Kansas Secretary of State Kris Kobach, sent a letter to the 50 US states and the District of Columbia requesting details from voter rolls including: names, addresses, dates of birth, political affiliation, last four digits of social security number, voting history since 2006, criminal convictions and military status.
